Landfills release greenhouse gases over time, and any form of source reduction or waste diversion mitigates the magnitude of greenhouse gas emissions. Recycling is a particularly effective method of waste disposal because material reprocessing requires less energy use than original processing. Collection Methods The New York City Department of Sanitation (DOS) picks up the majority of Columbia’s waste and recycling through a collection system on the Morningside Campus. All buildings within the Morningside Campus enclosure bring waste, plastic, glass, metal, paper, and some cardboard to a centralized location where the DOS picks it up for free. The City does not measure the amount that they pick up, so Columbia University only has records of private collection for waste and recycling on campus. In 2009, the University changed the way in which ‘sharps’ waste was collected, replacing single-use containers with re-usable containers. When full, these containers are robotically emptied, sanitized and reused. A single container may be used as many as 500 times. In fiscal year 2013, about 15,725* lbs. of glassware, over 174,828 lbs. of electronics, 8,237 lbs. of batteries, 487 gallons of solvents, and 20,926 lbs. of light bulbs/lamps were recycled. Surplus Reuse when possible is used on campus or alternatively, items no longer needed or in use are given to schools or local non-profit organizations with priority to organizations affiliated with Columbia Community Service. Whatever remains unclaimed goes to the Build It Green, NYC Waste Match program, which includes non-profits in the other four boroughs. Columbia also partners with the Institutional Recycling Network (IRN) where changed out dorm furniture and used equipment – like kitchen equipment is given. In the past equipment has gone to several countries in the Caribbean and to disaster relief in Haiti. More information is on the housing, dining and environment.columbia.edu website. Additionally, the Work/Life bulletin board, similar to an internal Craigslist, allows Columbia staff, faculty, and students to post personal household and office items to buy, sell, swap or reuse. http://worklife.columbia.edu/forum The undergraduate EcoRep program partners with Facilities and Housing for Give and Go Green and Facilities hosts Clean and Go Green. (*This is the amount that Columbia Environmental Health and Safety sends out through the Chemtracker program. This number does not reflect lab glass sent to the Department of Sanitation NY).

John Jay Dining Hall, Ferris Booth Commons, Faculty House, and Catering Services donate excess food and leftovers to City Harvest, the city supplier for food banks. Typically Columbia donates about 300 pounds a week of starches, vegetables, and sometimes meat. Smaller quantities are donated to a local homeless shelter, Broadway Community. In addition to food, Dining Services and University Events donate surplus kitchen equipment, including pots, pans, China, and larger restaurant equipment through the Institutional Recycling Network (IRN). Columbia Dining also works with Columbia Community Impact Food Pantry. Every Friday, volunteers cook a meal for 75-100 homeless and low-income guests. Columbia Dining donates packaged items so that people who visit can go “grocery shopping.” Lastly, the spring move-out donation drive, Give + Go Green, accepts canned goods which it also donates to food banks and local charities. Various food drives are conducted through the year, particularly in the holiday season.

Columbia Dining is contributing pre-consumer food scraps to an in-vessel composter the Rocket, that has been installed in Ruggles Hall. It is expected to produce about 160 gallons of compost in each two-week cycle based on an estimate of 400-lbs. of food scraps. Additionally, Columbia Dining recovers and recycles about 4,000 gallons of frying oil annually through The Doe Fund’s Ready, Willing, and Able resource recovery program. All oil collected is recycled into biodiesel. Lamont-Doherty Earth Observatory campus hosts a “backyard compost project”. The project got under way with more than $400 in donations from scientists and staffers. The three-bin system, built of wood, chicken wire and fiberglass, receives from 60 to 100 gallon containers of food scraps each week from cafeteria food preparation and lunch scraps from two campus buildings.

Members of the student-run Food Sustainability Project sometimes run a composting initiative where they compost post-consumer food waste. The group then uses the soil produced from their compost to fertilize their community garden. Columbia Dining also recycles all used trans fat-free cooking oil. They have partnered with The Doe Fund, through their Ready, Willing, and Able resource recovery program. Columbia Dining recycles about 4,000 gallons annually and all oil collected is recycled into biodiesel.

Operated by the undergraduate EcoReps, students can drop-off compost at designated times. Lamont-Doherty Earth Observatory campus hosts a “backyard compost project”. The project got under way with more than $400 in donations from scientists and staffers. The three-bin system, built of wood, chicken wire and fiberglass, receives from 60 to 100 gallon containers of food scraps each week from cafeteria food preparation and lunch scraps from two campus buildings. Lastly, Columbia hosts a NYC Greenmarket farmer’s market that has compost collection. Every Sunday, from 8am-1pm, Columbia community members can drop-off fruit and vegetable scraps, non-greasy food scraps (rice, pasta, bread, cereal etc.), coffee grounds & filters, tea bags, egg and nut shells, pits, cut or dried flowers, houseplants and potting soil that will be transported to one of several NYC compost sites. The food scraps are transformed into a fertile compost for use on local urban farming and gardening projects.

*Waste totals were calculated using the NYC Open Data Recycling & Diversion data set from the Department of Sanitation. Recycling totals were calculated by adding up Columbia's total recycling, compost and reuse tonnage for the DSNY district.
